GUN LOCKING MECHANISM (OPTIONS) Russian patent published in 2022 - IPC F41A5/00 

FIELD: weaponry.

SUBSTANCE: locking mechanism of the gun contains a tide, an axis of the return spring, a return spring, a gun frame with guides and a stop of the return spring. The barrel has the possibility of a short reciprocating motion. The combat projections engage with the corresponding combat grooves made on the inner surface of the shutter-casing provided with guides. Means for locking the shutter-casing relative to the barrel includes an oblique groove and a guide pin. The tide is additionally provided with lugs and is made together with the axis of the return spring, which is equipped with a clutch placed on the axis between the tide and the return spring. The barrel is additionally provided with guides and a cutout made on the lower outer side, in which the tide of the return spring axis is located. The engagement of the lugs of the lug of the axis of the return spring with the corresponding combat grooves of the shutter-casing is implemented by means of locking the shutter-casing relative to the barrel, which ensures that the axis of the return spring is skewed with a tide during a short translational movement of the axis of the return spring, joint with the barrel, or when the axis of the return spring is rotated with a tide during a short translational movement of the axis of the return spring, joint with the barrel.

EFFECT: increasing the accuracy of shooting from a gun.
